Subjective And Objective

 

Maybe the mind-body problem approaches resolution?

 

Causality

Causes and effects are not identical and are only empirically and contingently connected. There would be no logical contradiction if water were to remain liquid or were even to become solid above 100 degrees Centigrade, although, in the latter case, a new molecular theory would become necessary.

 

Causality of Consciousness

Electrically firing, chemically interacting neurons causes consciousness although some other cause might have been found. Disembodied consciousness is not logically impossible although a "pure spirit" would be a subject but not an object of consciousness and therefore would be undetectable. 

 

Subjective Experience

Given that a particular organism is conscious, there must be something that it is like to be that organism. See What Is It Like To Be A Bat? My subjective experiences are what it is like to be this organism. Every organism knows what it is like to be one organism and no other. If that is the case, then subjective experiences cannot exist independently of the organism.
